2, the stacked setting of pneumatic separator deep bead of the present invention extends to above lightweight thing discharging opening downwards from induced duct periphery always, the cross section of deep bead is hollow round table shape, air outlet connects an induced duct in lightweight thing sedimentation warehouse, and lightweight thing effectively can be carried out sedimentation collection by this structure.
3, the junction in the present invention between heavy thing collection bucket and wind-force separation bin is coaxially uniform arranges air inlet, by wind concentration to lightweight thing outlet conveying, can reduce eddy current.
4, scientific structure design of the present invention rationally, system run all right, screening efficiency are high, processing speed is fast, effectively carries out being separated of lightweight thing and heavy thing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
Based on a density sorting system for lightweight thing and heavy thing in house refuse, its density sorting system comprises pneumatic separator, cyclone separator and air-introduced machine 2; Pneumatic separator comprises heavy thing collection bucket 15 and wind-force separation bin 8, heavy thing collection bucket is packed in wind-force separation bin lower end, junction between heavy thing collection bucket and wind-force separation bin arranges air inlet 16, and the junction furtherly between heavy thing collection bucket and wind-force separation bin is coaxially uniform arranges multiple air inlet.Heavy thing collection bucket lower end is shaped with the outlet of heavy thing, and wind-force separation bin upper end is shaped with lightweight thing outlet 7, and the oblique sidewall of wind-force separation bin is shaped with charging aperture 9; The lightweight thing outlet of pneumatic separator connects the tangential material inlet 6 of cyclone separator by pipeline, the air outlet of this cyclone separator connects air-introduced machine by pipeline, this air-introduced machine connects a blast pipe 1, lightweight thing discharging opening 19 connects a lightweight thing belt conveyor 20, the charging aperture of pneumatic separator connects a material distributing machine, this material distributing machine comprises ingredient conveyor 10 and feed funnel 11, and the heavy thing outlet of pneumatic separator connects heavy thing belt conveyor 13 by a heavy thing discharging auger 14.Cyclone separator comprises a lightweight thing sedimentation warehouse 17, this lightweight thing sedimentation warehouse external wall of upper portion is shaped with tangential material inlet, air outlet 4 is shaped with in lightweight thing sedimentation warehouse upper end, this air outlet connects an induced duct 18 in lightweight thing sedimentation warehouse, stacked deep bead 5 is provided with in the lightweight thing sedimentation warehouse of induced duct periphery, lightweight thing sedimentation warehouse lower end is shaped with lightweight thing discharging opening, the stacked setting of deep bead extends to above lightweight thing discharging opening downwards from induced duct periphery always, described deep bead is connected with lightweight thing sedimentation warehouse inwall by gripper shoe 3, the cross section of deep bead is hollow round table shape.
The course of work and principle:
The house refuse of the heavy thing 12 and lightweight thing 21 mixing that pass through the adjoining dimensions of sorting in early stage is greatly about 2cm, ingredient conveyor is expected on even by the feed funnel of material distributing machine, in the oblique feeding pneumatic separator of rubbish that heavy thing and lightweight thing mix by ingredient conveyor, lightweight thing rubbish material is blown afloat by the air sucked from pneumatic separator air inlet by air-introduced machine, and the transport auger that heavy thing directly falls pneumatic separator lower end is transported by belt conveyer.Lightweight thing enters air duct from pneumatic separator upper end together with air stream, entered from cyclone separator upper end along horizontal tangential by air duct lightweight thing and air stream, air-flow moves downward twist along cyclone separator, lightweight thing collides with baffle plate and wall under centrifugal action, and under the guiding of deep bead and the effect of gravity, fall to the lightweight thing discharging opening of bottom along deep bead and barrel, be transported to fertilizer producing system by belt conveyer.Under the effect of air-introduced machine, the pure air eliminating lightweight thing is discharged from center induced duct, is also finally discharged in outside air by air-introduced machine.
Below pneumatic separator 360 degree annular air scoop and adopt the design of air-introduced machine air inducing, effectively ensure that to enter air flow method in Gravity Separation machine even, and suitably can regulate the intensity of air-flow as required.
The effect of interception and guiding is played in many groups baffle arrangement design of cyclone separator inside to the lightweight thing in air-flow, effectively ensure that in air-flow, lightweight thing rapid subsidence is to the discharging opening of device bottom, and effectively prevent lightweight thing by the phenomenon again blown afloat.
